AUTOMATIG SWITCv BRQOKLYN, NEW YOB-Ii I? A2133 AUXILIARY CIRCUITS,

This invention has for its object to provlde an eutcrzizitic swijbci, "1 may aiso be pera bed manuaiiy, and which especially adapted for use wherever there is a ii'ciiiiiwhich into us iii any time should :1 break occur in the main circuit as for example main and. ziuxiiiaiy dynamo circuits, or main and auxiliary lighting circuits in a factory, dwelling or Z, the use being to automai-icaiiy switch in 1111 211i iliary dynamo should the iiiciii dynamic break down, and See second use, which E have illustrated iii the ein' w automatically switch in an ing circuit, e. a'betfiery c ii'cuit, break 000w: in ihe main circuit.

Nith the above and obhei' objects in View, I have devised the novel automatic swivcii which X Wili 310W describe refer-ring to accompanying, drawing "forming a, part this specification and using reference chameters to indicate the-several parts.

Figure 1 is a View partly in eie'vai-ien, partly in section, anti pcctijy diagrammatic illustrating the noimai use of my novel. switch, the main circuitcontacts being i i the closed (112' 11'; position and the can iar' circuii: con'zacts being in the circuit position;v

A switch of the character described comprising an insulating body, an electromagnct seated therein and having acore provided at one end with opposite notches and high portions, :1 main circuit which en ergizes the magnet, contacts in said circuit, auxiliary circuit, contacts in said circuit one of which serves as an armature, a shaft in said core having endwise engagement with a main circuit contact and having a collar adapted to engage an auxiliary circult Contact, and a cross pin adapted to engage the notches and high portions of the core, and a sprin acting to retain the shaft in its normal post 5. A switch of the character described comprising an electro-niagnet, a plurality of coi'itacts, a magnet core ha ving opposite slots and high portions between the slots, and a shaft which is adapted to engage said contacts, said shaft adapted to have rotary and longitudinal movement in said core and beiug pro'vided'with a cross pin which is adapted to engage said slots and high portions.

switch of the character described, inc; an electro-magnet, contacts at oopositc ends of said magnet, a magnet core I opposite slots and high portions hethe slots, and a shaft which is adapt engage said contacts, said shaft adapted to ed to have rotary and longitudinai niovement in said core and being provided with a cross pin which is adapted to engage said slots and high portions.

in testimony whereof I allin my signature.
